CAN FORNIING AND SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 549,693, dated November 12, 1895.

Serial No. 517,288. (No model.)

ings, is a specification.

My invention relates to improvements and additions to a machine for Can forming and soldering, for which Letters Patent of the United States No. 429,87 2 were granted to me June 10, 1890; and it consists in special mechanism relating to the operation of different parts, all of which may be best understood by reference to the accompanying drawings and specification, and more particularly to the claims, the obj ect being to improve the working of the machine as a whole and to make it more certain and better adapted to the requirements of the art as now practiced. These objects I attain by the use of the mechanisms shown in the accompanying drawings, in which- Figure l is a front elevation of my machine, from which parts not essential to the understanding of the invention are omitted. Fig. 2 is a side elevation showing parts that relate to iiuX-distributing mechanism. Fig. 3 is a side view, partly in elevation and partly in vertical section, and is intended toshow the clampopening device and the mechanism for operating the soldering-irons. Fig. 4 is a side view, partly in elevation and partly in vertical section, showing parts of the mechanism for operating the soldering-irons not shown in Fig. 3. Fig. 5 is a rear elevation of my machine, several parts not essential to the understanding of the present invention being omitted. Fig. 6 is an elevation showing details relating to the movement 'of the carrying-wheel. Fig. 7 is a plan showing the soldering-irons and their connecting parts. Fig. 8 is a front view enlarged showing the former and connected parts. Fig. 9 is a side view of the former and its connected parts. Fig. l0 is a view in elevation showing details. Fig. l1 shows in vertical section a part of one of the clamps and some of its connected. parts.

Referring to thev drawings, A A represent the main part of the frame of the machine to which the operating parts are attached. B

is a shaft supported by standards A A2, at-

tached to and rising above the main frame A A of the machine.l Upon this shaft B, which is fixed so as not to turn in its bearings, the carrying-wheel B is mounted and is free to turn upon it. V

The carrying-wheel B is' fully described in the specification of Patent No. 429,872, above .referred to, and therefore needs but a brief description in this specification.

The wheel B consists, essentially, of a flat disk loosely mounted upon the Xed shaft B and provided with a number of bosses B6, placed at equal distances from each other and from the shaft B'. ln the drawings, six of these bosses are shown; but any required number may be used. The wheel B also has upon its rear side a series of bosses B7, equal in number to the bosses B6. To the outer end of a shaft passing through each'of the bosses B6 a forming device is attached, the inner end being furnished with gears (not shown) so connected with the central stationary gears BS, Fig. 3, that as the carryingwheel B is made to rotate the said forming device will be revolved about the shaft B, but will not rotate on its own aXis. By this arrangement each of the forming devices will accurately to the path of motion of theliquid-flux distributer O17, Fig. l, and also subsequently to the paths of motion of the soldering-irons e e.

To operate the carrying-wheel B, I have provided the following-described mechanism A6, Figs. l, 5, and 6, is a shaft adapted to be rotated by any suitable motor, its motion being timed to correspond with the other moving parts of the machine. Upon this shaft A6 a crank-arm hw, Fig. 6, is mounted. A pin in the crank-arm works, as the shaft A6 rotates, a block hw, which slides in a crossgroove 71,15, made in the cross-'head k12. The cross -head k12 is provided with a vertical opening 71.14 to admit of its motion during the rotation of the shaft A, which it embraces. It is evident that as the shaft A6 'rotates the crank-pin of the crank-arm hw will cause the cross-head k12 to move up and down. The motion of the cross-head k12 is communicated to the connecting-rod h2, Fig. 5, and by it to the oscillating arm h3, which is free tomove present the seam of the can that it carries IOO e 549,6ee

on the fixed shaft B as a center. A pin 27 is iitted loosely to the end of the arm h3. One end of the pin 27 is iitted to engage with holes made in the bosses BT, which are bored to receive it. The motion of the arm 71.3 is suffin cient to carry the pin 27 back and forth through the arc M, stopping an instant at each extremity. The above movement of the pin 27 equals the distance between two of the bosses BT, or, in other words, the distance required to cause the carrying-wheel B to rotate sufficiently to take one of the formers and its can the precise distance required by the conditions of the machine. In this case the distance is onesixth part of a circle, there being six formers on the wheel B. The pin 27 has a groove across it to receive the upper end of the lever h4, Fig. 3, which is pivoted to the lever h3 at 2S.

The lever h4 is operated by a slide h5, rest ing upon the standards A A2 and guided by rectangular grooves in the boxes B2 B2, the said slide being provided with two proj ections or fingers 29 30, which grasp the ballshaped end 31 of the lever h4. A block 7L is secured to the slide h5 by suitable screws and is provided with a latch-pin hl, which is made fast to the said block and passes loosely through the guide hs. The end of latch-pin 7LT is turned to iit the holes in projections B7. The slide h5 and latch-pin hl are given an alternating backward and forward motion by the cam-rod hm, which is attached to the arm h by the stud 32. The arm 7L works upon a stud and is provided with a roller that is grasped between the projections 34 35 of the block h,

In operation, the arm h3 being in the position shown in Fig. 3, the slide h5 and latch-pin LT move forward, the latch-pin h7 entering one of the projections Bland thus locking the wheel B in position. At the same time the fin ger 30 moves the lever h4, causing it to withdraw the pin 27 from the projection B7, in which it had previously been inserted. The arm h3 then moves, carrying the pin 27 through the arc 27 B7, when the return motion of the slide h5 forces the pin 27 into another of the projections BT, and at the same time withdraws the latch-pin la7. The arm h3 in its return motion carries the wheel B with it, the operation being repeated with each revolution of the shaft A".

In the machine illustrated there are supposed to be six formers-that is, one on each of the bosses B B, Fig. l-although but two are shown in this figure. One of the formers is shown more in detail in Figs. 3, 8, and 9. (Sec also Figs. 10 and l1.) These formers are mounted upon plates l), called work-plates, in the specification of the patent above referred to, in which these are fully described. The plates l) have connected to them directly or indirectly the formers and their connected parts. The cylinder b of the former is bolted to the work-plate l) and is provided with two slots 7 7, and is slightly liattened on its lower side. A bracket b2, supporting two clamps L b, is secured to the work-plate b. The clamps b3 114 act to form the can-body (a sheet of tin cut to size to form the body of the can) about the cylinder. A bracket b5 is secured under each former and supports two levcr-loeking arms D (1,pivoted upon the screws 1l 1l, and also pivotally connected by the toggle-1 oint 117. The arms b '(16 are provided with grooves or slots 12, Figs.8 and l0, and the ears 13 of the clamps b3 Il* are provided with studs carrying rollers 14,which work in the slots 12 of thelocking-arms. The clamps lfz Uare closed about the cylinder b bythe forked piece l1", which in rising to the position shown by corresljionding dotted lines strikes the clamps h3 b and carries them up and forces them about the cylinder, the rollers 15 an d 1G working against the clamps. The clamp b4 is closed first, as the roller 1G passes closer to the cylinder than the roller l5. The clamp b3 is iually closed bythe projection b9 striking the pin 17 of the toggle-joint U" and forcing it up past its center. The fork be immediately descends after closing the clamps to allow the wheel to make its motion.

I will now describe certain improvements in the formers.

The bracket b5 (see Figs. 8, and 10) is extended downward, and provided with a guide-groove D15 to guide the toggle-pin 17 and insure the opening of both clamps b3 ZJ" at the same instant.

bw is a guide bolted to the frame A and car rying two anged rollers to loosely grasp the shank of closing-fork bs.

b is a guide bolted to frame A bybolts passing through slots, and carrying two iianged rollers b18 D18, to loosely grasp the sides oil fork D8. The bolts and the slots are adapted to permit of adjusting the guides D to close the clamps,so as to lap the can-body either to right or left, as desired. (Fig. 8 shows can-body being lapped to right.)

b1", Figs. 8 and ll,is a cap secured byscrews to the clamp and arranged to hold a piece oi non-tinnin g material h2 upon the clamp.

It has been found diliicult to adjust the position of stud 13 so as to give clamps correct pressure upon cylinder b when acted upon by arms U". To facilitate this adjustment I have provided a screw b21, Fig. 1l, which passes through the clamp and rests against the stud 13.

For opening the clamp Ihave thc followingdescribed device: k, Figsl and 3, is a hand or socket adjustably attached to a bar k', which is connected by a rod 7a2 to a lever 7a3, which lever is pivoted to a part 7a4 of frame A and has its upper end passed through an opening in the end of latch-slide r". rlhe bar 7c is also connected by a universal joint 755 to a camlever k, which has one end pivoted to the frame A and carries a pin and roller to work in the grooved cam k7. When latchslide h5 moves to latch the carrier-wheel B, the motion it transmitted by lever 71:8 and rod k2 to the IOO IIO

hand ZZ', causing the hand to grasp the pin 17 of toggle-joint 67. The hand Zo is then pulled down by the cam k7 until the toggle-joint 67 and arms 66 are in the position shown in Fig.

10, when the hand is immediately raised,t he clamps 63 61 falling open, as shown by dotted lines in Fig. S.

As it is sometimes desirable or even necessary to use a liquid iiux instead of resin, I have designed a mechanism for this purpose, which I will now describe: A tank 014, Figs. l and 2, is supported by a forked bracket 015, which is secured to end of shaft B. The ends of bracket C13 pass upward in front of soldering-irons to intercept any drops of solder that may be thrown out by the irons. The top of tank 011 is made in form of a tray to catch such solder as may drop from the irons. A cock c1(i regulates the flow of fiux,which drops upon a brush C17, held by a clasp C13, which is attached to arm c3, by which and the parts C10 c11 013 it is operated. The arm c3 descends at the time required and causes the brush c17 to distribute the liquid flux along the seam, ready lfor the soldering action.

The mechanism for operating the solderingirons (shown in Figs. 3, 4, 5, and 7) may be described as follows: Each of the irons e c is held in a loop Z, which is adjustably secured to an arm Z', which in turn is clasped to the elbow-piece Z2, which slides in the cross-head Z3. The cross-head Z3 has a rod Z4, 4, eX- tending downward from it into the standard Z3. The lower end of the rod Z4 engages with one end of the lever Z3. The other end of the lever ZG is adjustably secured to the cam rod e111, so that by causing the cam-rod @10 to move they are raised or lowered. The cam for operating the cam-rod @10 is not shown in the drawings, as it is of ordinary construction and does not require description. A guide-pin Z7, secured to a projecting arm Z11 of standard Z5 and passing through a hole in the cross-head Z3, serves to prevent the cross-head from turning out of position. A hand-lever Z3 is pivoted to the upper end of the guide-pin Z7 and connected by a hook Z9 to the under side of the cross-head Z3. The hand lever Z3 is used for lifting up the cross-head Z3 and the soldering-irons e e. To hold the lever and the irons up out of the way I have a notch in the standard, as shown at Z111, Figs. 4 and 5. The soldering-irons e c are given a rubbing motion by a back-and-forth movement imparted to the elbow-pieces Z2 Z2 by the links Z13 Z13, cross-bar Z13, bent lever Z11, and cam-rod e3.

By the mechanism above described the soldering-irons are kept constantly in a horizontal position, thereby insuring a more even distribution of solder on the seam.

Two soldering-irons are shown in the drawings, adapted to operate on two cans at the same time; but one may be used alone if preferred.
